Free screening: “Passive House Revolution”, Mon. April 14 in LIC

Free Screening of Documentary on Super-Efficient Buildings, Monday, April 14, 7 PM Coffeed, 37-18 Northern Blvd., LIC, NY 11101

Note: This is a Resilience NYC Meetup Event – register here.

Resilience NYC Meetup hosts a free screening of documentary “Passive House Revolution,” its NYC premiere. Special guest after the screening is architect Tom Paino, who turned his LIC home into a super-efficient but controversial Passive House.

It’s part of a series of sustainability film screening and discussion events this spring at Coffeed Cafe, on the second Monday of each month at 7 PM. Coffeed, downstairs from the famous Brooklyn Grange rooftop farm, is providing free coffee and home-baked pastries for the events.

Buildings use nearly 50% of all energy used in North America today. The Passive House standard has been spreading across Europe for 20 years, a set of practices for building and retrofitting structures that use 80% less heating and cooling energy than average, much less than those from LEED-certified buildings, a green building standard common in the US. Climate scientists say we need to reduce our CO2 emissions by 80% as quickly as possible. Spreading the Passive House standard will be an important part of our response to climate change.

Following the screening, we’ll hear from architect Tom Paino, who renovated his Long Island City row house to become the first Passive House in Queens. As the NY Daily News and Queens Brownstoner noted, some Queens residents found the dramatic black, grey and white tile facade to be unattractive. However, the project was hailed in an extensive and positive review by US Dept. of Homeland Security.

There will be a facilitated discussion about how to make our neighborhoods more sustainable and more resilient. A resource guide with links to existing NYC programs will be provided.

Component Award proves Passive House windows profitable

Twelve winners to be honoured at the International Passive House Conference

(Press Release, Passive House Institute, 3 April 2014)

Darmstadt, Germany. The winners of the first ever Passive House Component Award have been selected and a total of twelve Passive House windows will receive recognition. The real winners, however, are the building owners, for the results of this international competition demonstrate that it is possible to save money with highly efficient building components. Manufacturers offered their products at retail prices including installation for an example building. For each of the four categories, “PVC,” “Wood,” “Wood/Aluminium,” and “Aluminium,” the overall investment and energy costs saved in comparison with standard windows were the decisive factor. The Award will be presented at the International Passive House Conference taking place from 25 to 26 April in Aachen, Germany.

In the “Wood” category, the joint first place winners are the Slovenian manufacturer M Sora for their Natura Optimo XL window and the German window company Pfeffer for their Pfeffer RPS window. The Holz-2-Holz window by Freisinger-Optiwin of Austria took second place. In the “Wood/Aluminium” category, the Smartwin Compact by Lorber-pro Passivhausfenster of Austria and the Futura by Bieber-Optiwin of France came in on top, followed by Freisinger-Optiwin again, this time with the Alu-2-Holz window.

The first prize in the “PVC” category went to German producer Hilzinger FBS GmbH for their VADB-Plus 550 window. The Pural eco 90 by Pural GmbH and the Frame 90 WI by Raico, both from Germany, were the winners in the “Aluminium” category. Special prizes went to German producers Passivhaus Transfer (dHPt), for their Delta Plus Cold Climate window (“Wood/Fibreglass, Synthetics”), Wiegand Fensterbau, for the glazing set in the DW-plus systems (“Innovative Glazing”), and Pazen Fenster + Technik, for their ENERsign arctis (“Lowest Heat Losses”).

“We are delighted at the level of active participation in the competition and congratulate the winners,” declares Dr. Wolfgang Feist, Scientific Director of the Passive House Institute – organiser of the Component Award competition. A total of 41 entries made it clear that Passive House windows are very attractive financially for building owners. “Overall cost savings of more than 25 percent, spread over the life span of the winning products, are possible. With Passive House quality products, the energy revolution becomes not only affordable, but even profitable.”

“Energy efficient, high quality components are an essential building block for the success of Passive House. It is important that these products provide not only convenience and comfort, but also economic advantages. We have proven this with this Award,” says Dr. Benjamin Krick, Head of Component Certification at the Passive House Institute.

The prizes will be presented by Dr. Wolfgang Feist at the Eurogress in Aachen. Many of the prize-winning windows will be exhibited by the manufacturers at the accompanying Component Exhibition which will take place from 25 to 26 April 2014, parallel to the International Passive House Conference.

New York and Philadelphia Projects among Finalists for Passive House Award 2014

Designers from around the world are honored as finalists for the international Passive House design award, including our friends in Brooklyn, Long Island, and Philadelphia.



Passive House Award 2014: Finalists confirmed


Winners will be announced at the Passive House Conference in Aachen

(Press Release, Passive House Institute, 28 March 2014)

Darmstadt, Germany. The finalists of the Passive House Award 2014 have again proved that world-class architecture and the Passive House Standard complement each other perfectly. An international jury made the final selection from approximately one hundred submissions. The winners in a total of six categories will be announced on 25 April in Aachen, Germany, at the 2014 International Passive House Conference. A list of all finalists can now be viewed on


The jury selected seven buildings in the category Office and Special Use Buildings: the RHW.2 Passive House high rise in Vienna (ARGE Atelier Hayde / Architektur Maurer & Partner); the Natural Heritage Centre on the German island of Rügen (Architekt Stöger); an artist studio in Long Island, New York (Ryall Porter Sheridan Architects); an extension of the Maximilianeum in Munich (Léon Wohlhage Wernik); the Syd Energi headquarters in the Danish city of Esbjerg (GPP Arkitekter A/S); the Kunstmuseum in German historical town of Ravensburg (Lederer Ragnarsdóttir Oei Architekten); and the Correctional Centre in Korneuburg, Austria (Arge Dieter Mathoi Architekten & DIN A4 Architektur).


The finalists in the category of Single Family Homes hail from Auckland, New Zealand (Jessop Architects); Sint-Niklaas, Belgium (BLAF architects); Espoo, Finland (Kimmo Lylykangas Architects); and Philadelphia in Pennsylvania, USA (Plumbob). The Apartment Building category saw finalists located in Hamburg (Huke-Schubert Berge Architekten), Munich (Allmann Sattler Wappner Architekten), and Berlin (Deimel Oelschläger Architekten Partnerschaft), Germany.


Three projects in the Educational Buildings category made it into the finals: the Riedberg Secondary School inFrankfurt, Germany (Ackermann+Raff); a seminar and apartment building in Goesan, South Korea(ArchitekturWerkstatt Vallentin); and the Montessori School in Aufkirchen, Germany (ArchitekturWerkstatt Vallentin, R. Grotz, R. Loibl, H. Walbrunn). The jury also selected three finalists from the retrofit projects submitted: a terraced house in London (Paul Davis+Partners), an office building in the French town of Saint-Étienne (Atelier d’architecture Rivat), and a terraced brownstone in Brooklyn, New York (Fabrica718 / Studio Cicett Architect).


In addition to the 20 individual buildings that made it to the finals, a Passive House Region, favoured by the majority of the jurors, was directly chosen as a winner in the Urban Planning category. This project will also be honoured with the Passive House Award at the International Passive House Conference. An important aspect of this particular project, as with all the winners, was its emphasis on the Passive House Standard in conjunction with the use of renewable energies – an approach that fits with the “Nearly Zero-Energy Building” of the European Building Directive.


The 2014 Passive House Award has been put on by the Passive House Institute under the patronage of the German Federal Ministry of Economic Affairs and Energy and within the framework of the EU project PassREg (Passive House Regions with Renewable Energies). Certification verifying compliance with the Passive House Standard (or EnerPHit Standard in the case of retrofits) was a prerequisite for participation. The jury was thus free to focus solely on the architectural design of the projects in its evaluation.

AAVs (Air Admittance Valves)





Venting of plumbing fixtures has been a standard in the design and construction of plumbing systems in New York City buildings for almost a century. Vented plumbing stacks are required to maintain a water seal in a fixture’s trap, the U-shaped section of pipe below a sink, which creates an air lock that prevents the entrance of sewer gasses. Without the trap’s water seal, noxious gasses would make their way up through your pipes, out of the fixtures, and into your home.

When a toilet is flushed or sinks and tubs drain water, this water travels down the sewer pipe. Without a vent pipe, a vacuum effect would result which would draw all the water down from the trap, allowing the noxious gasses to pass through. Traditionally, venting is achieved via a second pipe connected to the sewer stack – the vent pipe. It allows air in above the trap, equalizing the pressure on both sides of the trap, thereby allowing it to hold water and keep sewer gasses out of the building.

The function and construction of a typical vent stack system has remained the standard in NYC for about a century. However, in this age of increased awareness of energy efficiency and building performance, there are now products and technologies that give us better functional performance, simplify construction and increase energy efficiency. Air Admittance Valves (AAVs) are one of such products we feel outperforms the typical vent stack system.

Air admittance valves are pressure-activated, one-way valves that can be used in place of typical vent stack systems. The AAV is a non-mechanical valve that is located just above the fixture’s drain, fitting within a bathroom vanity or cabinet, out of view. It eliminates the need for a second vent pipe, reducing construction costs while increasing usable space.


Sans titre 3

On a larger building-wide scale, fewer vents result in fewer exterior roof penetrations. A typical plumbing vent system requires numerous roof penetrations, which compromise the building’s thermal! envelope (and each require additional insulation/air-sealing work). Additionally, one less vent per stack results in a smaller shaft and more usable square footage (and less air-sealing work). Furthermore, fewer vents result in less potential for leaks or failure.

Although not in New York City, AAVs have been used for decades and allowed in practically all US jurisdictions as a suitable alternative to plumbing stacks. The construction cost savings of eliminating vent stacks, penetration waterproofing, and airsealing stacks can be reinvested into improving the building envelope. The reduction in energy use from a high performance thermal envelope will provide cost savings throughout the life of the building: a win for both the owners and the city as a whole.

Over many years, Air Admittance Valves have been a proven method to improve upon the use of typical vent stack systems both in energy efficiency and construction cost. NYPH are currently working with the Urban Green Council to provide documentation to the NYC Department of Buildings to get permission for AAVs to be used in NYC construction.


On April 9th, NYPH will hold a presentation on AAVs, more information and sign up HERE.

Climate protection at the municipal level – a ten-point program for the building sector

The Passive House Institute issues a position paper for municipalities to act on global climate protection.


Darmstadt, Germany  March 13, 2014

Climate protection at municipal level: ten-point plan for the building sector

Position paper of the Passive House Institute regarding the use of Passive House technology as a contribution to climate protection in the building sector for cities and communities.

Climate change affects us all. In order to effectively tackle climate change, we must reduce our energy consumption significantly in the long term. This means efficient use of available energy and placing maximum priority on saving energy. Cities and local authorities are important actors when it comes to climate protection – at the local level, with every individual, every community, in every region. On average, about 40 % of the total energy consumption in industrialized countries is used for buildings. That is why significant improvement of the energy efficiency of buildings has considerable impact on the overall assessment of a town, municipality or urban district in terms of energy. Due to the long service life of buildings, a consistent approach is especially important in this respect. For more than 20 years, the Passive House Institute has committed itself to the advancement of the Passive House Standard, with which an improvement of 40 to 75 % in the energy consumption for heating and cooling of new builds can be achieved; in the case of refurbishments, reductions of 75 to 95 % are commonplace. The Passive House Institute has compiled the following 10 points to support and to trigger effective climate protection measures in the building sector at the local level:

1) New public buildings belonging to the city or local authority will only be built to the Passive House Standard in future. As far as possible, renewable energies will be used: additional upgrading of buildings with renewable energies to the Passive House Plus level (with fully sustainable energy supply) or Passive House Premium (with a surplus of renewable energy generated). The same applies for new builds rented by cities, i.e. the aim is to achieve a heating and cooling demand of less than 15 kWh/m²/a each. Refurbishments of owned or rented buildings will only be carried out with Passive House suitable components, meaning refurbishment to the EnerPHit Standard or a retrofit yielding a reduction in energy usage by a factor of 10. Renewable energies will also be taken into account in the case of refurbishments.

2) Land belonging to the local authority will only be sold on condition that construction will take place according to the Passive House Standard, or that refurbishment will be carried out using Passive House components, with the integration of renewable energies. Suitable verification (e.g. preliminary planning with the PHPP) should be provided.

3) Municipal urban planning will be adapted to the climate. The topographic situation of the building, its compactness and its orientation in relation to the sun, the prevailing wind direction, and the shading will all be taken into account. Such planning will be supported by binding specifications of mechanical and building energy supply systems.

4) Housing companies belonging to the municipality will be obliged to construct their new buildings in accordance with the Passive House Standard and to modernise their existing building stock using Passive House components, with integration of renewable energies.

5) The city or local authority will create its own financial incentive programme for investors and private building owners in order to encourage participation in climate protection measures through the construction of Passive House buildings, through refurbishment using Passive House components, and via the use of renewable energy sources.

6) Quality assurance by means of milestones will be used to check whether the required standard of work has actually been provided. Milestones include, for example, planning approval, execution planning, initial site meeting post completion of the building shell, second site meeting post completion of the airtight building envelope, completion of the building, assessment of technical measurements, independent certification.

7) Climate-neutral urban districts based on the Passive House Standard will be developed as pilot projects.

8) Informational events and further training will be offered to communicate with investors, builders, building owners (commercial and private), residents, architects, craftsmen, local companies, urban planning experts, and political decision makers. Providing consultations prior to the issuing of building approvals will be mandatory. Appropriate advisory facilities will be set up.

9) The use of energy-saving household appliances and building system technology, as well as replacement of electricity intensive technology will be encouraged, for example, through information campaigns or financial incentives.

10) Communications on construction to the Passive House Standard and the use of renewable energies will be firmly anchored in municipal public relations strategies and campaigns on the subject will be implemented. For a wider impact, the energy consumption of individual buildings will be monitored and the findings published as examples to follow.

The Passive House Institute is convinced that the sum of these measures will contribute significantly to the reduction of energy consumption and greenhouse gas emissions in the building sector while substantially reducing municipal expenditures. There are many examples of cities and municipalities throughout Europe and in other parts of the world that have already implemented such principles either in full or in part and have profited from the resulting contribution to climate protection. This paper is intended to encourage other cities and local authorities to initiate reforms in building sector practices in their own jurisdictions, as climate change affects us all.

Renewable Energy in a Passive House: New PHI Classifications

While “Net Zero Energy” is a seemingly simple concept, in reality calculating the
energy balance of a building requires complex accounting. Photovoltaic panels produce
most of their electricity during summer days, while buildings consume energy all the
time, especially during cold nights. The Passive House Institute (PHI) takes Net
Zero to the next level by accounting for energy storage requirements and making sure
that wasteful buildings can’t simply add huge PV arrays to claim “Net Zero” status.

At a New York Passive House presentation last week, German architect Kay Künzel
presented a case study of a home automation system that prioritized using PV energy
directly instead of exporting it to the grid. For example, the system would run the
dishwasher while the sun was shining to avoid having to use non-renewable grid electricity.
PHI’s new classification takes this kind of optimization into account, in a way that “Net Zero”

In New York we are very aware that Net Zero penalizes multistory buildings in an urban
environment. PHI’s new classification system eliminates the large urban building penalty
by basing the renewable energy potential on the lot area, rather than the total floor area
of a building.

Wolfgang Feist will present more details at the 18th annual Passive House Conference in April.

New Passive House categories also rate building energy gains

Concept to be presented at the 2014 International Passive House Conference

Darmstadt/Germany. The efficiency of the clearly defined Passive House Standard
has been proven with thousands of buildings – in order to also offer a reliable means
of orientation regarding the additional use of renewables, the Passive House Institute
now plans to introduce new categories. These will not only take energy demand into
account, but also energy supply through, for example, solar panels. In this way,
Passive House offers an attractive solution for the energy revolution while also serving
as the basis for the “Nearly Zero Energy Building,” mandatory for all new builds
throughout the EU as of 2021.

“A building that produces more energy than it consumes is not only possible, it is often
very sensible,” says Dr. Wolfgang Feist, Director of the Passive House Institute. The
way in which this is calculated, however, is of critical importance when it comes to
setting criteria for a standard. “A building that produces an energy surplus in summer
doesn’t necessarily have a good energy balance. Photovoltaic systems typically yield
very little energy in winter, which is exactly when the most energy for heating is used.
Therefore, the calculation only works when the energy demand itself is also very low.”

Energy efficiency thus remains the basis for the Passive House Standard. In addition,
the new building categories will rate the coverage of the remaining energy demand by
renewable sources. Taking the example of a single family home, the new “Passive
House Plus” label confirms that about as much energy is produced as is consumed,
whereas the “Passive House Premium” seal denotes an energy surplus. Dr. Feist will
present the details of these new Passive House classes at the International Passive
House Conference, taking place from 25 to 26 April 2014 in Aachen, Germany.

“The new classes view energy production in relation to the potential of the particular
building in question,” emphasises Dr. Benjamin Krick, senior scientist at the Passive
House Institute. “A single family home built to the Passive House Standard can
achieve an energy surplus relatively easily; for an apartment building it is much more
difficult, as such buildings have a far smaller roof area available per square meter of
living space. It is for this reason that the new classes calculate energy production in
relation to the ground area occupied by the building.” A future-oriented scenario in
which only renewable energies are used throughout the electrical grid serves as
reference for the evaluation.

Compared to conventional buildings, the Passive House Standard, as developed more
than two decades ago, saves an average of 90 percent of heating and cooling energy.
Highly efficient windows, ventilation systems and superior insulation of the external
walls keep Passive House buildings comfortable year-round. In winter, the remaining
energy demand can mostly be covered by passive heat sources such as the sun’s
rays. In summer, these same Passive House features serve to keep buildings cool.

The criteria of the Passive House Standard are straightforward and clearly defined.
The performance of the standard has been proven by numerous monitoring projects.
Some 50,000 Passive House units have been built worldwide. Economic reasoning
often serves as the motivation to build a Passive House: additional investments are
normally paid back through energy savings in a matter of years. A further advantage
for occupants lies in the outstanding levels of comfort Passive Houses offer, through
consistently warm inside surfaces and optimal air quality.

Green Building Conference Sets Its Sights High

June 17th, 2014 in New York City

Kavanagh Tuite ArchitectsPassive House is a building standard that promises 90% reduction in heating and cooling energy usage compared with existing building stock. Proponents of the standard cite energy savings, comfort, health, and affordability among the reasons Passive House is gaining traction among green building and energy specialists.
Translated as “Passive House” in English from the German “Passivhaus”, the name conjures an image of a wood-framed home. Though most U.S. certified Passive Houses are homes thus far, the NY14 Passive House Conference and Expo seeks to add a new perspective to this image.  Register here.

New York Passive House in cooperation with the Passive House Academy has announced a one-day conference and expo for June 17, 2014 at the Metropolitan Pavilion at 125 West 18th Street in New York City. The focus of the conference will be big buildings such as multi-family, schools, stores, and office buildings – including a high-rise Passive House proposed for New York City’s Roosevelt Island by Cornell University. Presentations will showcase completed projects from around the world by leading practitioners. The event will also serve as an expo of leading products and service providers that cater specifically to the U.S. Passive House market.  Both the conference and expo are focused on delivering information to building professionals.

The conference program offers 10 educational sessions running from 9:00 am to 5:30 pm. The international character of this global building standard is represented with presentations by practitioners from Austria (Lang Consulting), Belgium (Architectes Associes), Ireland (Kavanagh Tuite Architects), the UK (Architype), New
York (Steven Winter Associates) and other US regions (PassivScience). Conference organizers anticipate 15 speakers in total, bringing a broad array of expertise within Passive House building field, focusing on in-depth analysis of the obstacles and opportunities Passive House building provides. Over 30 manufacturers or service providers are expected to be represented in the expo, providing a comprehensive overview of specialized products and knowledge essential for low-energy Passive House building. The expo will run from 8:00 am to 6:30 pm with an open bar cocktail reception beginning at 5:30 pm.
